Version 3.03
The War Declaration UI has been completely reworked. It now displays the total strength of the vassal participants on each side, the reasons for why a vassal joins the war or declines their call to arms, and the vassal's primary title.

Title Holders - When a vassal would lose any of their titles as a result of a war, they will be called to arms.

Enable/Disable Call to Arms - You can now disable your vassals from being called into your wars temporarily by using a decision, which can help you avoid War Exhaustion penalties.

Capturing direct vassals of a war leader will now grant 2% war score for each vassal captured by the opposing side.

Each time a civil war happens in a realm, vassals will receive an "Internal Turmoil" opinion penalty to represent the recent instability. There is a new game rule added to disable this.

War Exhaustion penalties now vary based on why a vassal was called to arms (i.e if they are just bordering the enemy realm or if they have a vested interest in it).

Added a global variable for More Interactive Vassals that other mods can check using "has_global_variable = miv_is_loaded", which should make compatibility patches easier.

Version 3.02
Defiant Vassals - Vassals can refuse to join a war based on their relations with their liege, and can also block their own vassals from joining.

Treacherous Vassals - When allied with the opposing side, vassals can be called to war against their own liege and vice versa.

The war declaration UI will now indicate which vassals decline their call to arms, rather than not showing them in the list at all.

Civil War Rebalance - More vassals will remain neutral during civil wars.

Off-by-default game rules now indicate the default value for clarity.

Version 3.01
Garrison Size - The size of all garrisons can be reduced by 25%/50%/75%/100%, shortening the time it takes for an army to siege a holding.

War Participants (Off by Default) - War participants who join a war after it starts can call their own vassals to arms, though with much weaker obligation.

Opinion Modifiers can now stack, calling vassals into too many wars will greatly decrease their willingness to join you.

Peasant uprisings and similar levy-based rebellions will now scale based on the Levy Reduction setting.

Cleaned up a lot of the mod's code. Error and debug logs should now be a lot cleaner, and game performance should be smoother as a result!

Version 3.0
Levy Size - Levies from all sources can be reduced by 25%, 50%, 75%, or 100% to place more emphasis on the Men-at-Arms counter system and reduce overall army sizes.

Levy Reinforcement - The rate of levy replenishment can be reduced by 25%, 50%, 75%, or 100%, making losses from combat more impactful.

Bannermen (Off by Default) - All direct vassals are eligible to be called to arms, but with a much higher chance of declining based on several factors.

Indirect Vassals (Off by Default) - In a civil war, a vassal may call on their own vassals to support their commitments to the loyalist or rebel factions, who will accept or decline based on several factors.

Levy Contribution - The amount of levies that vassals provide to their liege is reduced by a multiplier of 25%/50%/75%/100%.

Updated the descriptions for the custom game rules in this mod.

Added a new game rule category to organize the custom game rules in this mod, making it easier to find and configure them in the settings menu.
